科學美國人 60 秒聽力練習:魚油補劑
科學美國人 60 秒英文文本
It ’ s been touted for its healthful, anti-inflammatory properties. It ’ s been recommended for helping ease the pain of arthritis, preventing cancer and slowing memory loss. But some recent studies of fish oil show that it may not always act as advertised — and that you can sometimes have too much of a good thing.
First, the latest news. Researchers spent 18 months following almost 300 patients with mild to moderate Alzheimer ’ s. Some took fish oil, others a placebo. And there was no difference cognitively between the two groups. The study is in the current Journal of the American Medical Association.
It ’ s a mixed bag on cancer. A study of more than 35,000 post-menopausal women found that those who took fish oil seemed half as likely to develop breast cancer as those who didn ’ t. That work was in the July issue of Cancer Epidemiology, Biomarkers & Prevention.
But a study in the October 15th issue of Cancer Research found that mice with inflamed bowels developed colitis and aggressive colon cancer when they were given high doses of fish oil.
So, fish oil might in fact have a healthful role in some circumstances. But you don ’ t want to swallow every fish story.
科學美國人 60 秒中文翻譯:
魚油因其有益健康、抗抑炎癥的功效而為人推捧。它被大力推薦用於協助減輕關節炎疼痛、預防癌癥、減緩記憶衰退等。不過,最近的研究表明,魚油或許並沒有像廣告宣傳的那樣具有神效,有時候好東西攝入太多也會過猶不及。
對魚油的研究發現食用效果好壞參半
首先,最新消息:研究人員花落 18 個月來追蹤近 300 名輕度至中度的阿茲海默癥患者。其中一些人服用魚油,另一些服用安慰劑。而兩組對照並無認知差異。這項研究結果發表在最新一期《美國醫學會》雜志上。
這對癌癥患者而言可謂喜憂參半。一項由 3 萬 5 千多名絕經後婦女參與的研究發現,服用魚油的婦女比不服用魚油的婦女患乳腺癌的幾率似乎少瞭一半。這項研究發表在 6 月份的《癌癥流行病學、生物標記物與預防》上。
但是,10 月 15 號出版《癌癥研究》發現,腸道發炎的小鼠在攝入高劑量的魚油後會患上結腸炎和轉移能力極強的結腸癌。
如此說來,魚油實際上可能隻在某些情況下起到助益健康的作用。當然,你也大可不必把這些研究結果看得過重。
1. inflammatory adj. 煽動性的 , 發炎的 , 炎癥的
2. arthritis n. 關節炎
3. placebo n. 安慰劑
4. post-menopausal 絕經後
5. colitis n. [ 醫 ] 結腸炎
